The invention relates to a thermal insulated building element, which together with connecting elements is suitable for making a building system quickly, which is also suitable for housing and exact fastening of any reinforcement.

Due to the development of building technologies, introducing of new materials, great changes have taken place in the building industry. The requirement of proper thermal insulation values in building systems providing high quality buildings in a short time is an ordinary claim nowadays. The most frequently used material in the construction industry is still concrete as the proper thermal insulation of concrete can be ensured.

In the state of art Hungarian utility model HU U 2348 makes known a thermal insulated building element. Here the solution is, that the building element is covered with polystyrene panels on both outer and inner sides, and the space between the polystyrene panels on the outer and inner sides is filled with load-bearing concrete and occasionally reinforcement is put into the concrete. The parallel polystyrene panels on the outer and inner sides are fixed by connecting cross clamps and on the side edges of the polystyrene panels groove profile and bolt profiles fitting each other are formed.

The characteristics of the solution made known there is, that the connecting cross clamps have rectangular cross section, the thickness of which is preferably 1.5-5 mm, width 20-50 mm and there are perforations of 6-12.5 mm size in the middle line of the width corresponding with the thickness of the building element in the distance of 120, 250, 300, 360 mm and at each end of the cross clamp holes of circular shape housing the closing pipe or section holes housing the closing bolt are formed. In the polystyrene panel there are holes of vertical position from the inner side towards the outer side conforming with the rectangular section of the connecting cross clamps, into which the connecting cross clamps are pushed in the position of connecting the polystyrene panel and there are parallel circle shape holes or section shape holes of horizontal position in the outer side of the polystyrene panel going through the opening crosswise, closing pipes or closing bolts fastening the polystyrene panels are fixed to the hole of circle or section shape and at the side edges of the polystyrene panels there are protruding ribs on both sides of the bolt-profile, whereas on both sides of the groove profile there are arched, lengthwise channels.

German publication DE 196 33 111 makes known a connecting element, made preferably of recycled plastic, which is applied on the outer and inner surface of a case element in the form of a T-shape slot, distributed above the whole surface and fixed to each other in a stabile way. Due to the bit surface of connection during casting of concrete of filling in of concrete no deformation occurs.

This application makes known furthermore a building element to be applied in a building structure, which building element comprises bodies of plane and/or broken and/or curved surface or joining surfaces of hollow or partially hollow bodies. The building element is characterized by that, it has at least one outer surface forming the surface of the building structure and has furthermore an inner surface, and has at least one complex rib-surface, the value of the angle of which is 90°≧γ>0°, preferably an acute angle, for example 5° . . . 15°. In the building element on this part of the rib-surface the size of the section surface parallel with the outer building surface is increasing and one part or the whole of the section of the rib-surface is point-symmetrical. There is a part of the outer building surface, the shape of which is a K side polygon, where K≧3, for example a triangle, square, pentagon, hexagon.

We had to take into consideration when creating the thermal insulated building element shown in FIG. 34, that in case of the basic formation, the solution is not suitable for malting a girdle. To make it possible, we apply a possible embodiment of the formwork according to the invention. It can be seen in the figure, that a hollow 27 suitable for housing the relative reinforcement and forming the girdle is formed in the girdle 26 elements. The girdle 26 elements are connected with the connecting element 19, on which the framework 18 is placed.

FIG. 46 shows a possible embodiment of the building-in of the building element according to the invention. In special purpose buildings, such as very tall buildings, or freezing houses beside keeping thermal insulation characteristics keeping structural parameters is also necessary. It can be ensured by the solution according to the invention such a way, that the polystyrene elements 1 and the connecting elements 19 as well as with the help of the framework 18 solutions in accordance with statical structural measurements.

In case of a possible preferable embodiment of the solution according to the invention formation of the interim supports of the skeletal frame takes place with the help of a steel bar led between the parallel guiding elements in wave-form. Another possible preferable embodiment is, when forming of the interim supports of the skeletal frame is solved by a ladder-like straight connection between the parallel guiding elements.

Connecting of the lateral and bottom-top edges of the polystyrene elements is solved by a long plastic strap, which is put into the lengthwise groove made into the edges of the polystyrene elements, and when pushed together it flips into the edges of the polystyrene elements and flexibly closing there. When assembly takes place, the reinforcement is simply pushed between the polystyrene walls 1, then the plastic straps are pushed as well. This solution makes possible the application of the prefabricated interior reinforcements, for example application of steel grid. Notches in the walls and sides of the polystyrene element walls are formed with heat cut or grooving.

The advantage of the solution according to the invention is, that it makes possible easy and quick production of various thermal insulated walls in-site. Structural formation makes possible beside simple and durable connecting of polystyrene elements the placing and positioning of several reinforcements, grids, loadbearing structures.
